As shown in Figure 12, we observe that these data flows have been successfully recognized by some middle boxes between the GGSN
and the Internet such as Firewall and OCS (Online Charging System) where all traffic is composed of IP packets.
"The solution allows encapsulating the generated packet data within GTP headers and transmitting through the gateway points such as SGSN & GGSN
, or SGW & PGW.
The ad hoc network domain connected to the GGSN
of Core Network (CN) by Wireless Access Gateways (WAGs) using GPRS Tunneling Protocol (GTP) which is a group of IP-based communications protocols used to carry General Packet Radio Service (GPRS) within UMTS CN.
* SGSN: SGSN for the user and GGSN
to provide packet routing functions, it will be the base station controller (Controller BSC, BaseStation) sent the packet sent to other SGSN or via GGSN
external Internet network transmission.
Core network connectivity emulates the SGSN operations to communicate with the UMTS GGSN
* has P-CSCF and Associated Home of Visiting GGSN
in the same network.
The agreement, of which financial details were not available, stipulates that Elephant Talk will provide a full Mobile Virtual Network Enabling system that includes a Gateway Support Network (GGSN
), IN (Intelligent Networking) Platform, a Customer Relationship Management platform (CRM), a Full Rating & Billing Platform and a STP/Signaling Platform for AirTouch to launch its services in the US.
The GPRS core network connects to IMS network through gateway support node (GGSN
-- For the 3G network, the Bridgewater PCRF supported the test of Cisco's GGSN
. The test simulated one million users accessing the network at the same time at a sustained rate of 18,000 packet data protocol (PDP) activations per second.
The enhancements include support for 2G and 3G GGSN
(Gateway GPRS Support Node) and the new Alcatel-Lucent 5780 Dynamic Services Controller (DSC), which provides the 3G and LTE PCRF (Policy Charging and Rules Function).
Focusing on operator needs, the NE40E USR is capable of integrating the functions of BRAS, GGSN
, DPI, SBC, video real-time monitoring and stream cache technologies which provide operators more flexibility during network deployment.
The expansion of network is centred upon deploying Ericsson's Packet Core Network, including both SGSN and GGSN
nodes, and Ericsson's Mobile Softswitch Solution, the company said.
